How to fix leaking sink hose?

I have water dripping from the hose despite the knob being tighten.

Do I replace #1, #2, or both? I already tighten the turning knob as well as the nut (#1) and it's still leaking. Any suggestion is much appreciated.

That's not a hose. That's a supply line. If it is the supply line leaking not the valve replace the supply line with a stainless steel braided supp;y line.

You will need to check the size of the connection at the valve and if it is compression or flare. You will probably need a basin wrench to disconnect the old supply line at the faucet.

Yes, it is the supply line. However, if I tighten the nuts and knob, water shouldn't be coming to the supply, correct? That is why there is a close valve with a knob to turn off water, right?

You need to change the valve, they are generally considered unrepairable.

Your valve is called a 5/8" (1/2" nominal) compression inlet valve.
The outlet is 3/8" compression and is common.

You'll need a puller to get the old compression ring off.
You could try to find the same valve and use the old nut and ring, keeping them on the pipe.
I don't recommend that usually but it might work and will be easier on you.

Hanyone, so if I'm going to replace that whole thing, I'm going to need a puller, correct? What's a "puller" looks like? Do I have to apply some type of glue when putting the new one in?

I'm going to try to see if I can find the same exact valve so I don't have to replace that nut. Thank you so much for the help.

If you don't know what a puller is I wouldn't recommend you pull the old nut and ring off.
You could run into a can of worms and have to call out a plumber.
The old pipe could be badly deformed if the old valve was over tightened, making replacing the valve difficult.

If you use a similar valve apply some Teflon paste to the new valve's male threads.
Just snug up the new valve to the old nut, it doesn't need to be very tight.

Okay, so just to confirm, the valve is referring #1 in my picture, correct? Or is it both #1 and #2? The part that I need to find a similar size so I don't have to use a puller to pull out the nut. Again, much appreciated.

Water is on the supply hose above the valve. I would concentrate my efforts on the connection to the sink as the leak appears to be after the valve.
